Transition of fertilizer application and agricultural pollution loads: a case study in the Nhue-Day River basin
Rapid socio-economic development in suburban areas of developing countries has induced changes in agricultural waste and nutrient management, resulting in water pollution. The study aimed at estimating agricultural nutrient cycles and their contribution to the water environment. A material flow model of nitrogen (N) and phosphorus (P) was developed focusing on agricultural activities from ...

Uses of winery and distillery effluents in agriculture: characterisation of nutrient and hazardous components
ABSTRACTTwenty-one samples of winery and distillery effluents were collected from different Spanish winery and distillery industries. Electrical conductivity, pH, redox potential, density, organic charge (chemical oxygen demand, biological oxygen demand, total, volatile and suspended solids, oxidisable organic C and polyphenols) and contents of plant nutrients and heavy metals were analysed. The ...

Nitrate leaching from a potato field using adaptive network-based fuzzy inference system
The conventional methods of application of nitrogen fertilizers might be responsible for the increased nitrate concentration in groundwater of areas dominated by irrigated agriculture. Appropriate water and nutrient management strategies are required to minimize groundwater pollution and to maximize nutrient use efficiency and production. Design and operation of a drip fertigation system ...

Nitrogen Fertilizer Industry: March towards getting Greener
AbstractA major concern to the growth and development of fertilizer manufacturing industries all over the world is on the environmental front. Serious efforts are underway to make fertiliser technologies most environment friendly and sustainable with the help of research and development initiatives in technology as well as management of facilities. Technology plays a key role in improving the ...

Enriching African soils key to boosting crop yields
In African countries where farmers have access and can afford to buy fertiliser, there is a profound difference in agricultural yields, a feature in Nature notes. The red soil found across much of the continent is low in organic matter and key nutrients, and intensive farming in Sub-Saharan Africa is estimated to have removed 22 kilograms of nitrogen, 15 kilograms of potassium and 2.5 kilograms ...

What is Soil EC Sensor?
Soil EC (Electrical Conductivity) sensor is an essential tool for modern agriculture, enabling farmers to optimize crop yields by measuring the nutrient levels in the soil. EC sensors measure the soil's ability to conduct electricity, which is a proxy for soil salinity and nutrient content. This article will explore the basics of soil EC sensors, their applications in agriculture, and the factors ...

Worms & Black Castings for an Abundance of Healthy Crops
Earthworms are more than just good fishing buddies, they naturally incorporate organic material into the soil, increasing the amount of microbes, improving the health of the soil, and increasing plant productivity. Both worms and black castings from worms provide your garden or farm with a nutrient rich and robust environment, able to withstand harsh weather conditions such as drought and the ...

New methodical way for sustainable farming systems using treated sewage water in irrigation in Jordan
Most scientific approaches in research are done under objectified, controlled conditions. Such experiments do not reflect the everyday reality of farmers. Moreover, experimental research in agriculture does not always reflect the interests of Jordanian farmers. Another type of research is therefore needed. We need research that integrates Gamma and Beta sciences, farmers and scientists and the ...

From the Farm View - V33 Farms - Keith Melnyk
Keith Melnyk of V33 Farms has been farming with his dad John, and brother Wayne, for approximately 30 years. Together, they run a 3,000 acre farm in Alberta’s Peace Country, east of Manning, where they grow canola, wheat, peas, oats and some forage grasses for ...

Building a Business with Nutrient Management
Laurelbrook Farm is a third-generation dairy farm in East Cannan, Connecticut. The Jacquier family owns 275 acres, and rents an additional 2,500 acres for cropping, to support a herd of 830 cows. The family began composting three years ago as part of the farm’s nutrient management plan, as well as to determine the market for compost in the area. “In 2003 the Environmental Protection ...

Application of nitrogen and phosphorus criteria for streams in agricultural landscapes
Efforts to control eutrophication of water resources in agriculturally dominated ecosystems have focused on managing on-farm activities to reduce nutrient loss; however, another management measure for improving water quality is adoption of environmental performance criteria (or ‘outcome-based standards’). Here, we review approaches for setting environmental quality criteria for nutrients, ...

Regenerative agriculture and climate change
The term “regenerative agriculture” is gaining prominence in climate-related conversations. It dates back to the 1980s when Robert Rodale coined the term, “regenerative organic agriculture” as way to express that organic should be more than simply avoiding chemical inputs. The term has been defined and re-defined by many different authors, sometimes describing very ...

Evaluation of greenhouse gas emissions and design of mitigation options: a whole farm approach based on farm management data and mechanistic models
Agricultural activities are important sources of nitrous oxide (N22O), methane (CH4) and carbon dioxide (CO2). They contribute approximately 10% of the total emitted greenhouse gases (GhG) in the European Union. We search for evaluating GhG emissions at the farm level and designing mitigation options. As emissions occur at many stages within the farm operation, it is crucial to consider nutrient ...

What are the advantages of organic fertilizer production machine to make fertilizer from farm wastes?
Organic fertilizer production machine makes manure from farm wastes, mainly for livestock manure, kitchen and domestic garbage and other organic wastes to carry out aerobic high-temperature fermentation, kill harmful bacteria, add beneficial bacteria, use the activity of microorganisms to biodegrade and decompose them, so that the organic wastes can be transformed into usable organic raw ...

Valuation of nitrogen retention as an ecosystem service on a catchment scale
An ecosystem service approach was used to study the water purification service exemplified by impacts of land management scenarios. Nitrogen retention was calculated in two agricultural catchments by the dynamic Integrated Nutrients in Catchments (INCA)-N model. The monetary valuation was based on purification efficiency of artificial wetlands. The set of scenarios were based on existing ...

Nutrient sorption dynamics of resin membranes and resin bags in a tropical forest
Plant root simulator (PRS) probes, a resin membrane technology, are increasingly used to measure soil nutrient availability in agricultural and nonagricultural systems. Like other resin technologies, the charged surface is meant to sorb nutrients until saturation; however, there is evidence that it acts as a dynamic exchanger in soils with low nutrient availability. This study compared the ...

Introduction to Efficient Manure Management Solution
In the realm of sustainable agriculture, effective manure management is a critical component. As farming practices evolve, so does the need for innovative solutions that not only enhance productivity but also minimize environmental impact. Tianzhong Machinery has emerged as a leading supplier of manure separation systems, providing farmers with cutting-edge technology to revolutionize their ...

The manage database: nutrient load and site characteristic updates and runoff concentration data
The 'Measured Annual Nutrient loads from AGricultural Environments' (MANAGE) database was developed to be a readily accessible, easily queried database of site characteristic and field-scale nutrient export data. The original version of MANAGE, which drew heavily from an early 1980s compilation of nutrient export data, created an electronic database with nutrient load data and corresponding site ...

Organic and mineral input management to enhance crop productivity in Central Kenya
Organic resources (ORs) are important nutrient inputs in tropical agriculture. Combined with mineral fertilizers, they form the backbone of integrated soil fertility management. This study was conducted to determine the medium- to long-term influence of OR quality and quantity on maize productivity and to evaluate the occurrence of additive benefits in terms of extra grain yield produced by the ...
